CVE-2017-13084 wpa_supplicant: reinstallation of the STK key in the PeerKey handshake

The MITRE CVE dictionary describes this issue as:

Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Station-To-Station-Link (STSL) Transient Key (STK) during the PeerKey handshake, allowing an attacker within radio range to replay, decrypt, or spoof frames.

Statement

This issue did not affect the versions of wpa_supplicant as shipped with Red Hat Enterprise Linux 5, 6, and 7, as wpa_supplicant's implementation of the PeerKey handshake mechanism is incomplete and does not allow the installation of a key into the driver.
